After the events of Halloween, the word "Chamber of Secrets" began to be talked about in the mouths of every student at Hogwarts. Granger succeeded in asking some information in the history of magic class, and as a ghost, Professor Binns ushered in the most attentive and frequent period of his teaching career, and every student wanted to ask something special.

"Enough, don't ask about the Chamber of Secrets." "It's just a stupid myth, and if you ask something that has nothing to do with the class, I'm going to deduct points," Professor Binns said.

So, when Professor Binns satisfied the students' curiosity, the history of magic returned to its usual lethargic and slow rhythm, and other than that, the week passed very peacefully, and Lawrence had been looking for a chance to talk to Ginny, but in the past few days, whether it was outside the first-year classroom or waiting in the saloon, they had never met, and on Saturday morning, Lawrence went to Percy to inquire about the situation,

"Ginny has been having a hard time lately, and I found her crying in the women's room the day before yesterday," Percy told Lawrence, "the same toilet with crying myrtles, and he was worried that Ron would be expelled from school, and he was worried about the petrified cat."

"I need to talk to her, do you know where she is?" Lawrence asked with a frown,

"I don't know, but I just met her," Percy replied, "and she said she wanted to be alone."

"Okay, thank you." Lawrence thanked him and hurried to the girls' restroom on the second floor, where he guessed that maybe Ginny might be there.

But Lawrence didn't find anyone, and the golden peach lady in the toilet was nowhere to be found, Lawrence looked at the stagnant water on the toilet floor, looked around but couldn't find the source of the leak.

"Mr. Rovande." A serious voice came from behind him, it was Professor McGonagall,

"Ugh...... Hello, Professor." Lawrence said,

"What are you doing here?" Professor McGonagall asked, pointing to the toilet door, "Don't you see the sign?"

"Nothing, Professor." Lawrence replied that it occurred to him that the toilet was very close to the place where Lady Loris's petrified was, and that Professor McGonagall's office was on the second floor, and of course patrolled the surrounding area.

"I suppose you're looking for clues about the killer, right?" Professor McGonagall said, "Don't bother, it's not something students are supposed to do."

"Uh, yes Professor." Lawrence replied that he couldn't tell Professor McGonagall that he had come to the girls' restroom in the middle of nowhere to find Ginny.

"If I were you, I'd go to the hall right now for a bite to eat," Professor McGonagall said in a relaxed tone, "Wait for the Gryffindor vs. Slytherin Quidditch match, you won't forget, will you?"

"Oh, good professor." Lawrence replied, and he turned away, but instead of eating in the hall or going to the court, he walked towards the Gryffindor saloon, where he met many students who were going in the opposite direction to him, and they were all about to go to the court to watch the game.

When he walked into the Gryffindor saloon, he happened to meet Colin, a first-year freshman, who was holding an old camera, and left in a hurry because he was angry and his face was red.

Lawrence saw a small round table in the saloon with a somewhat distorted camera. Weasley sat on an armchair with his face covered and sobbed,

"What's wrong?" Lawrence asked, "Colin seems angry?"

"I borrowed his camera from Co-Lin," said Ginny, crying, "but I accidentally broke it, and Colin had to go and get the old camera......" (Note 1)

"Uh, how did you get to be like this?" Lawrence asked curiously,

"When I came to my senses, the camera was in the furnace," Ginny cried.

"Ugh...... Ginny, I've always wanted to ask you," Lawrence asked, "and on Halloween, you...... Did you take our map?"

「…… What map?" Ginny looked up blankly, her red and swollen eyes staring at Lawrence,

"On Halloween morning, we're in the saloon, and you know the map is ......in my suitcase," Lawrence reminded, but he felt that Ginny's blank expression didn't seem fake.

"Halloween? I didn't get out of bed that morning...... I slept until noon, and my roommate woke me up......" Ginny replied blankly,

"What?" Lawrence asked, surprised, "I saw you crying in the saloon early that morning."

"Impossible...... I remember the night before, I was in my dorm room...... Keep a journal until ......you fall asleep," Ginny replied, wiping away her tears, "Do you want to go to a Quidditch match together?" I want to apologize to Colin again......

"Okay, let's go." Lawrence didn't continue to ask, he didn't think his memory was wrong, but he didn't think Ginny was lying, this contradictory sense of incongruity made him wonder,

They left Gryffindor Tower and walked towards the first floor, there was a thunder outside the window, dark clouds blocked the sun, and it began to rain heavily, the cold wind and rain poured in through the window, and the lack of sunlight made the corridor look a little dark, passing the second floor, Lawrence, who was walking in front, suddenly stopped,

"Ginny, stop and don't go over." Lawrence said calmly, on the floor in front of him, there was a figure lying - it was Colin, Ginny let out a scream, and then fell to the ground, Lawrence took out his wand, and walked cautiously towards Colin,

"Was it attacked?" Lawrence poked Colin with a magic battle, Colin held up the old camera, his expression was terrified, Lawrence held up the magic battle, he thought about the twins he met on the Hogwarts Express on the day of admission, and the exciting prank life after entering the school, they evaded Filch's pursuit again and again......

"Call the guards!"

A majestic four-legged creature flew out of the tip of Lawrence's wand and flew towards the headmaster's office, Lawrence put away the magic battle and stood in place, he silently turned his head to look at Ginny, who began to sobble again, (Note 2)

There was a burst of fire, and Phoenix Fawkes appeared beside Lawrence with Dunburydo,

"Good thing Fawkes is here, Professor." Lawrence said, "But you're coming so fast."

"I just didn't go to the game, and Fox offered to give me a ride." Deng Bulido said that he crouched next to Colin's "petrified" and asked, "Is it 'petrified' again?"

Lawrence nodded, he frowned and looked at Ginny, he felt a strange malice emanating from Ginny, and Ginny just looked up and looked at Colin with a frightened face, Dunburydo waved his wand to make Colin float,

"Follow me, Mr. Rovander and Miss Weasley." Dunbulido said, turning to the phoenix, "I need you to inform Mineva, Fawkes."

There was another burst of fire, the phoenix disappeared without a trace, and Deng Buliduo commanded Colin, who was floating in the air, to take them to the hospital room together,

"What's wrong, Headmaster?" Madam Pomfrey asked in a low voice, and they placed Colin in a hospital bed,

"Another attack." "The students have spotted him, and I'd like you to give Miss Weasley some calming potion."

"Okay, come with me, Miss Weasley." Madam Pomfrey said that Ginny followed her obediently.

"Follow me, Lawrence." Dunburydo whispered as he took Colin's camera from his hand, and then some screens jumped over to cover Colin's hospital bed, and they walked to Professor McGonagall's office, which was closest to here.

"What's going on? How did you end up there?" Deng Buliduo asked, so Lawrence told him what had happened,

"I think there's something wrong with Ginny." Lawrence hesitated for a moment, but he was still wondering if he should tell Dunburydo about the map of the living point, "I feel like she'...... It's very strange."

"I think so, too, that I found a faint trace of black magic on Miss Weasley's body." "But it's not surprising, a lot of things have a hint of dark magic in them, even Hogwarts."

"But she wasn't there at the time of the incident." Lawrence replied, and for the first time he intuitively realized what Dunburydo said, "I see a lot more than the average person." How much, at least he couldn't see the traces of black magic on Ginny's body,

"Yes, but I think the Chamber of Secrets is open," Dunbulido said, "and the question is how?"

"Professor, can't you ......?" Lawrence asked, somewhat embarrassed,

"No, Lawrence," replied Dumblido solemnly, and Lawrence was silent, "I want you to understand that everyone is innocent until proven guilty." (Note 3)

"I made a mistake...... Lawrence said, "I lost one...... The map, I think the secret language has been cracked, and it has very important information on it."

"So, you think there will be new victims soon?" Dunbury's sharp blue eyes looked at Lawrence, and Lawrence could see that there was more to the blue eyes than to look at it...... wary

"That's what I think," Lawrence replied, and Dunburydo was silent, as if he was weighing something, and then he seemed to have made some kind of decision,

"I need your help," Deng Bulido said, "and if this happens, closing the school is the only option......

「…… But until then, I'll probably be removed from office," a flash of anger flashed in Dunburydo's blue eyes, "When the time comes, I want you to trust someone."

"Who?" Lawrence asked,

"Severus," Dunburidor replied, "Severus. Snape."

Author's note: The next cycle of the high school exam.

Note 1: Colin, who was originally killed at night, is now killed, and it is not difficult to leave a person alone, just like in the fourth episode Harry cast a spell to tear Cedric's backpack.

Note 2: Lawrence didn't know where Dunbury was, so he went to the principal's office to find Phoenix Fox and asked him to bring the principal over.

Note 3: As Tom Murphy fifty years ago. Riddle.

Note 4: Just like Tom 50 years ago. Riddle, actually, I think it's very likely that Dumblido has found out that Ginny has a little problem, as in the book, in the hospital wing at the time of the Colin incident, Dumburido says 'It's not a question of who it is, it's a question of how.'"
